Seashield 70 System in Saudi | Denso Marine Pile Protection Saudi

Protecting a marine pile takes more than covering visible rust. The system must follow the pile’s shape, protect the surface beneath the wrap and withstand wear from the surrounding environment.

Nassguard supplies the Denso SeaShield 70™ System in Saudi Arabia for steel and timber pile protection. It combines a petrolatum-based corrosion barrier with a tough fiberglass outerwrap. Suitable applications include jetties, piers, docks, wharfs and bridge piles.

We supply contractors, technicians and marine maintenance teams across Riyadh, Dammam, Jubail, Jeddah and Al Khobar.

What Is the Denso SeaShield 70™ System?

The Denso SeaShield 70™ System is a multilayer marine pile protection system for standard to heavy-duty applications. Crews can apply it to wet surfaces or underwater, making it practical for structures where drying the pile is difficult.

The system uses three main protective components:

• Denso Paste S105™ helps displace surface water and fills irregularities that could leave gaps beneath the tape.
• SeaShield™ Marine Piling Tape forms the primary corrosion protection barrier around the pile.
• Denso™ Glass Outerwrap UV cures into a tough outer covering that provides mechanical and impact protection.

Compression film holds the fiberglass wrap firmly in place during curing. The wrapping materials accommodate round, square, hexagonal, octagonal and variable pile profiles.

Key Features of the SeaShield 70 System

The system combines close-fitting corrosion protection with an outer layer that withstands the demands of marine exposure.

• Underwater application allows crews to protect suitable submerged pile sections.
• Wet-surface compatibility reduces the need to wait for completely dry working conditions.
• Impact and abrasion resistance helps protect the corrosion barrier beneath the fiberglass wrap.
• UV-resistant outer protection supports use on exposed sections of marine piles.
• Conformable wrapping materials follow different pile shapes and changes in profile.
• Water-activated resin eliminates the need for on-site resin mixing.
• VOC-free materials suit projects that specify products without volatile organic compounds.
• Versatile exposure protection covers immersed, tidal and splash zones in marine, estuarine and freshwater environments.

Applications of the SeaShield 70 Marine Pile Protection System

The SeaShield 70 System suits new construction and maintenance projects where steel or timber piles need protection against deterioration and mechanical wear.

• Jetty pile protection supports maintenance work on suitable waterfront structures in Dammam.
• Port and wharf maintenance helps protect suitable piles serving marine facilities in Jubail.
• Pier and dock protection supports coastal maintenance projects in Jeddah.
• Marine infrastructure maintenance covers suitable waterfront pile applications in Al Khobar.
• Bridge pile protection suits appropriate river, estuarine and marine installations.
• Timber pile protection provides a protective covering for suitable wooden marine supports.
• New construction projects can incorporate the system into the specified pile protection programme.
• Project procurement teams in Riyadh can source the system through Nassguard for coastal and infrastructure work.

Pile Preparation and Protective Wrap Application

A sound installation starts with a clean, properly prepared pile. Plan access, material quantities and the wrapping sequence before opening the water-activated outerwrap.

• Remove living marine growth, loose corrosion, loose paint and other surface contamination.
• Smooth sharp projections and abrupt profile changes that could damage the wrapping materials.
• Fill pits and irregularities with Paste S105 or the appropriate profiling materials to prevent gaps beneath the tape.
• Apply a thin layer of Paste S105 across the area requiring protection.
• Wrap the Marine Piling Tape with its backing film facing away from the pile.
• Maintain a 55% spiral overlap, starting and finishing with two complete circumferential wraps.
• Activate and apply the fiberglass outerwrap, maintaining the required overlap and smoothing out wrinkles and trapped air.
• Extend the glass outerwrap at least 100 mm beyond the piling tape at both ends when the installation does not connect to another SeaShield system.
• Apply compression film under tension to hold the outerwrap in place during curing.
• Inspect the completed covering for continuous coverage, sealed overlaps and defects.

Certifications, Standards and Compliance

• ISO 9001:2015 – Quality Management applies to Denso’s manufacturing quality management system.
• ISO 14001:2015 – Environmental Management applies to Denso’s environmental management system.
• ASTM D1000 – Tape Testing covers the reported thickness, breaking strength and elongation properties of SeaShield Marine Piling Tape.
• ASTM G8 – Cathodic Disbonding Testing is the test reference for the tape’s reported cathodic disbonding resistance.

Inspection and Maintenance of Protected Piles

Regular checks help maintenance teams identify damage and arrange repairs before the underlying protective layers face further exposure.

• Inspect the outerwrap for cracks, impact damage, loose edges and open overlaps.
• Check areas near vessel contact and locations where floating debris may strike the pile.
• Examine the upper and lower terminations for movement or loss of coverage.
• Record damage with photographs and note its position on the pile.
• Repair damaged sections using a compatible repair method and the correct system materials.
• Arrange an engineering assessment when the pile shows significant section loss, timber decay or other structural concerns.

FAQs

1. What does the SeaShield 70 System protect?

It protects suitable steel and timber piles on marine structures, including jetties, piers, docks, wharfs and bridges.

2. Can crews apply SeaShield 70 underwater?

Yes. The system supports underwater and wet-surface application with appropriate preparation and installation.

3. Is the system suitable for square piles?

Yes. Its conformable materials accommodate square, round, hexagonal, octagonal and variable profiles.

4. Which layer provides corrosion protection?

Paste S105 and Marine Piling Tape form the primary corrosion protection layer. The fiberglass outerwrap adds mechanical protection.

5. Does the fiberglass outerwrap require resin mixing?

No. It contains a water-activated resin, so crews do not need to mix separate resin components.

6. Does SeaShield 70 restore a damaged pile’s load capacity?

The system provides protective wrapping. An engineer must assess any loss of load capacity and specify structural repairs where necessary.

7. What information should I provide when ordering?

Share the pile material, shape, dimensions, quantity, protection length, site conditions and project specification. Photographs also help explain the application.

Conclusion

The Denso SeaShield 70™ System combines a close-fitting corrosion barrier with durable fiberglass outer protection. Its suitability for wet and underwater application makes it a practical option for many marine pile maintenance projects.

Successful protection depends on proper preparation, continuous wrapping and careful inspection. Selecting the correct materials at the start also helps crews avoid gaps, shortages and installation delays.
